NEW YORK ( TheStreet) -- There are a lot of lessons to be learned from the craziness going on in the market right now. We're going to take a look at the facts as they present themselves at the current moment.We are finally starting to see some of the leading stocks begin to roll over a bit as are now in earnings season. Last week was the start of earnings season. Several big companies reported earnings: Alcoa ( AA), YUM! Brands ( YUM), JPMorgan Chase ( JPM) and Wells Fargo ( WFC) were the biggest ones. So I thought this would be a good time to analyze the company that deals with the four food groups here in America: fried chicken, pizza, root beer and tacos -- don't tell me you never eat this stuff! We're talking about YUM!, the owner of KFC, Pizza Hut, Taco Bell, Long John Silver, A&W, etc.
